Quesiton...has anyone successfully added a male to a sorority of females? I know in the past I have read about others doing this successfully but not sure exactly how many people have tried. Of couse, I am well aware of the risks of the male coupling off with a female and will probably start trying to kill the other females.

I would not risk this. It's dangerous enough having a sorority, if you add a male it guarantees trouble and injury. I am sure people who have done it need only wait. You can have fish together for years before they snap and kill each other.

People try, and they claim success, but usually it's very short lived. Breeders who have worked with generations of them have been able to keep some sibling males/females together successfully but even then it's risky. Oldfishlady is one of the few who successfully keeps multiple males and females together, I believe she has some pictures of them in her profile. She has spent many years and many generations in order to be successful.
